Spencer Soper, reporting for The Morning Call on the working conditions in Amazon’s Allentown, PA warehouse:

During summer heat waves, Amazon arranged to have paramedics
parked in ambulances outside, ready to treat any workers who
dehydrated or suffered other forms of heat stress. Those who
couldn’t quickly cool off and return to work were sent home or
taken out in stretchers and wheelchairs and transported to
area hospitals. And new applicants were ready to begin work at
any time.

An emergency room doctor in June called federal regulators to
report an “unsafe environment” after he treated several Amazon
warehouse workers for heat-related problems. The doctor’s report
was echoed by warehouse workers who also complained to regulators,
including a security guard who reported seeing pregnant employees
suffering in the heat.
